OVEN FOR OlL-BURNERS.

SPECIFICATION forming" part of Letters Patent No. 744,945, dated November 24, 1903.

Application filed August 27, 1902. fierial No. 121,256. (No model.)

To all whom it may oncern:

Be it known that I, HOLLING G. TUCKER, a citizen of the United States, residing at Hereford, in the county of Deaf Smith and State of Texas, have invented a new and useful Oven for Oil-Burners, of which the following is a specification.

This invention relates to ovens for oil-burning stoves; audit has for its object to provide an oven especially suitable to be used in connection with what is known as crude-oil burners, more particularly of the form shown and illustrated in Letters Patent of the United States granted to me on July 15, 1902, and

r5 numbered 704,669.

The improved oven,- which is the subject of my present invention, is provided with interiorly-arranged flue-plates forming passages through which the air heated by the burner may be permitted to pass directly in contact with the casing constituting the oven proper or with an interior casing, or with both, thus enabling the oven to be heated to any desired degree, dampers being arranged so as to perfectly regulate the passage of the hotair.

The invention further consists in the improved arrangement and construction of an overflow-basin which when weighted down by the overflow from the burner will automatically shut oll the fuel-supply, thereby avoiding all danger of accident resulting from an oversupply of the fuel-oil.

With these and other ends in view the invention consists in the improved construction, arrangement, and combination of parts,

which will be hereinafter fully'described, and

particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view, partlyin section and partly in elevation, of a device constructed in accordance with my invention. Fig. 2 is a vertical sectional view taken through the oven part of the device on the line '2 2 in Fig. 1.

Corresponding parts in both figures are indicated by similar numerals of reference.

1 designates the oven, which consists of a rectangular box or casing comprising the sides 2 2, back plate 3, top plate 4, bottom plate 5, and the door 6.

5 0 7 designates a hopper-shaped casing, the

with the front and rear edges of the bottom plate 5 of the oven, While the ends 8 8 of said hopperare extended beyond the end plates 2 2 of the oven and have upward extensions 9 9,the upper edges of which are connected by a top plate 10, with which they cooperate to form the exterior casing of the oven. The back plate 3 of the oven is extended laterally, as at 11, and upwardly, as at 12, to meet the rear edges of the plates 9 and 10. The front edges of the side plates 2 and 9 and 4 and 10 are likewise connected by plates, (designated, respectively, 13 and 14,) thus forming a complete space inclosing the three sides of the oven, as will be clearly seen by reference to the drawings. i

In the vertical side spaces 11 are disposed vertical flue-plates 15, which are supported between the front plates 13 and the extensions of the back plate 2, thus forming fines 16 and 17, which are disposed, respectively, between the flueplates and the oven-casing proper and between said flue-plates and the exterior casing. Dampers 18 and 19 are disposed at 7 the lower ends of the lines 16 and 17, so as to regulate the passage of the heated air therethrough.

The top plate 10 of the exterior casing is provided with suitable openings 20 for th escape of air.

The hopper-shaped casing 7, which extends downwardly from the exterior casing of the oven, is provided at its lower end with a cylindrical sleeve 21, through which extends the fuel-pipe 22, supporting the burner 23. This burner, as already stated, has been patented to myself and does not require to be described in detail. The sleeve 21is provided with draft-openings 24:, and it has at its lower edge an inwardly and upwardly extending flange or collar 25, in which is slidingly mounted a basin 26, which is of circular shape, so

4c and restored to operative position.

' vided with a crank arm or handle 29, which is connected, by means of a spring 30,-with a post or upright 31, having a stop 32, which is so disposed that when the arm 29 is held in 5 engagement therewith by the tension of the spring 30 the valve shall be closed. To open the valve, it is drawn downward against the tension of the spring and is engaged with a trigger 33, mounted pivotally at the upper IO end of an upright 34 and having a beveled end 35 to permit the arm 29 to be readily passed by and placed in engagement therewith. Another upright 36, mounted upon the support 27, carries a lever 37, one end of which has loose pivotal connection with the trigger 33, while its opposite end supports the vertically-sliding cup or overflow-basin 26, which may rest upon a block 38, so as to distribute its weight evenly upon the end of the lever.

The operation of thisinvention will be readily understood from the foregoing description taken in connection with the drawings hereto annexed. While thedevice is in use 2 the arm or lever 29 is normally in the position indicated by Fig. 1--that is, engaging the trigger 33, whereby the valve 28 is kept open and the fuel-oil permitted to enter the burner. The overflow from the latter I 0 enters the cupor basin 26, which rests, as described, upon the onter end of the lever 37. At a predetermined point the latter is overbalanced, thus raising the inner end of the trigger and disengaging the arm 29, which is instantly under the influence of the coiled by contact with the flame will ascend through the fines surrounding the oven-casing, and the passage through said fines may be so regulated by the dampers 1S and 19 as to subject the said oven-casing to a greater or less degree of heat, as will be very readily understood. Thus by opening the outer dampers 19 and closing the inner ones the hot air will pass through the outer fines and the oven will be comparatively lightly heated. By opening one of the outer and closing one of the inner fiues on either side the draft may be regulated in an obvious manner, while by permitting the hot air to ascend only through the inner fines and closing the other ones the oven-casing will be subjected to the greater available degree of heat.

I have in the foregoing described what I consider to be the preferred form of my invention; but I desire it to be understood that I do not limit myself with regard to the structural details of. the same, but reserve the right to any changes, alterations, and modifications which may be resorted to without detracting from the utility of my invention or departing from the spirit and scope thereof. Thus, for instance, it is evident that the front of the oven-casing proper is to be provided with a door, as shown in the sectional view Fig. 2, the ends of the damper-rods are to be provided with handles by means of which they may be conveniently manipulated, the front side of the hopper 7 is provided with an opening through which the burner may be reached for the purpose of conveniently igniting the fiame, and the oven with its related parts is to be supported upon suitable framework.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. An oven comprising an inner casing, an exterior casing surrounding the ends and top of the inner casing and forming within said exterior casing end spaces which are open at their upper and lower ends, vertical fineplates disposed in the end spaces and spaced from the inner and outer casings, and dampers independently controlling the passage of air through the fines thus formed.

2. An oven comprising an inner casing, an exterior casing surrounding the ends and top of the inner casing, and forming within said exterior casing end spaces which are open at their upper and lower ends, flue-plates disposed vertically in the end spaces thus formed, dampers independently controlling the passage of air and products of combustion through the fines between the flue-plates and the inner and outer casings, ahopper depending from the lower edges of the exterior casing, and a burner disposed in said hopper.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HOLLING G. TUCKER.
